- This invention relates broadly to covers '7 isters and for heat radiators, and it: has for its primary object to provide an inexpensive. l and attractive, cover or shield whichimay be f f readily applied to. a hot airregister or to a steam. or, hot water radiator to protect the theradiator. :whereby. the heated, air rising from the regwall "of a room, adjacent to the register orto the room.

With ,hese and other objects in new, the, invention resides in the features of construcof elements which willhereinaftr be fully described,,reference being had to the accompanying drawings, in which Figure 1 is'a fro'ntelevation of the inve'n tion applied to a hot air register;

Referring to said'drawings, 1 designates ,the usual" grille of a hot air register which maybe-of any approved d-esign,'the same belng generallyof arectangular-form, as shown. In carrying out the present invention, there is provided a back plate 2 which is open, as

. shown at 3, to provide a recess or opening adapted to fitabout the top and lateral edges the wall adjacent to and surrounding the re .ister, as is clearly shown in Fig. 1. The back 1928. Serial mg arm-j ofthe radiator grille and which rests against plate 2Jhas formed integrally therewith a top, 1 which, projects" forwardly therefrom and which is provided with a downturne'd flange or front wall member 5 having therein openings 6of any appropriate form. v The top 4 has downturned endpo'rtions 7 which against and are suitably 1 attached to side .1 plates 8, aslby rivets, spot-welding or brazing.

As shown in Fig. 2, theside plates Smay be given an ornamental contour. Said plates further serve to preventdirect circulation of thie hot air currents laterally from the register. V j Secured to theinner surfaces of theside plates are right angular bracketsor cleats 9 which constituteguides andsupport-s for awater pan 10 which is preferably in the form of a drawer. Said brackets are located at a spaced distance below the front wall member 5 to provide an opening through which I which; front wall projects at its ends beyond, the endsof the drawer and which is connected with the side walls of the drawer by a rep I entrant flange13, as shown clearly in Fig. 7 is a front elevation of the inventhis flange being adapted to impinge against the front edge of the side plates 8 and thereby limit the inward movement of the drawer so1that the back of the drawer will always be spaced from the back 2 of the casing to provide an open air space or passage 14, as is clearly shown in. Fig. 2.

brackets 18-which support the rear edge of the filter.

p I Alined horizontally withthe cleats or supporting brackets The air filter 20, as is most clearly shown in Fig. 6, comprises a rectangular frame 19 of stout wire, preferably more or less resilient, and a covering 20 of a suitable textile or woven material which fits around the frame 19 and is held distended thereby. The frame 19 has one side supported by the flange 17 and the other side by the bracket 18, the bracket preferably being somewhat lower than the flange so that the filter will be disposed in a slightly inclined position asshown in Fig. 2. Should it be desired to remove the filter for any purpose, as for cleaning, the rear edge can be moved upward slightly which movement will withdraw the front edge thereof from the flange 17, whereupon the entire filter may be removed "by d0wnward movement.

The heated air currents flowing outwardly through the grille of the register naturally take an upward course in which they engage the textile covering 20 of the air filter. Air which passes through the pores or interstices of the textile fabric is efiectually filtered, the particles of dust being caught by and adhering to the surface of said fabric; The air, so filtered, is turned rearwardly by the bottom of the water pan or drawer and rises through the air passage 14, thence to flow forwardly over the surface of the .Water in the pan or drawer and finally emerges through the openings 6 into the room. In this passage over the pan, the heated air vaporizes the water and the moist vapor is carried into the room with the heated air currents. It has been demonstrated that when the heated air is thus humidified, a lower temperature will keep the building comfortable so that less fuel will be required than in instances where the air is perfectly dry. Moreover, the humid air has no bad effects upon the joints of the wood trimming or of the furniture within the room.

The water pan or drawer 10 is, of course, provided with knobs 22 which give it an ornamental appearance and whichalso facilitate the handling of the same.

In the formof the invention shown 1n Figs.

4 and 5, there is employed the same casing,

the same air filter and the same water pan or drawer. In addition, brackets 23 are provided. at the ends of the casing to project inwardly therefrom over the radiator 24, and said brackets are provided on the under sides of their front and rear edges with grooved flanges or cleats 25 which form guideways in which plates 26 are slidably engaged. Clips 27 of a general U-shape type are attached to the under sides of these plates to fit over the nipples between adjacent radiator sections, as shown in Fig. 4, for supporting the device upon the radiator, the adjustability of the plates permitting the clips to be easily set to conform to the size of the radiator and the spacing of the sections thereof. While the back plate of the casing in this instance may be the same in all respects as the back plate 2 shown in Figs. 1, 2 and 3, it may be a continuous plate covering the entire back area of the radiator, and I have so illustrated it. The circulation of air and the filtering of the same is the same as that previously described. It will be particularly noted that when the device is applied to a radiator, the pan is close to the top of the radiator so that the Water will be effectually vaporized by the rising air currents. The dust pad or air filter is disposed between the radiator and the pan so that the air which plays over the water in the vaporizing pans is free of dust and, therefore, carries no dust into the room.

The rising air currents passing through the air filter are diverted to the rear of the pan so that. being permitted to discharge into the room through the front ofthe casing, they musttravel over, the top of the pan in absorbing contact withthe water vapor. The .air filter is easily removable from beneaththe water pan when it is to be cleaned, renewed, or repaired, and may be removed or inserted without in any Way disturbing the water pan;

also without disturbing the topof the casing.

In'the modification shown in Fig. 8, the water pan is wholly dispensed with and the air filter20 has its front edge mounted on a rearwardly directed flange 11 formed at the lower edge of the vertical wall member 5'.

The rear edge of said filter seats upon a bracket or brackets 18 mounted on the rear wall 2 of the casing. Heated air directed upward through or against the .filter is cleansed by impact with the latter, being thence directed forward into the room. What is claimed is 1. In an air filtering and humidifying atthe level of said pan, and means for filtering air passing to said vertical passage.

2. In an air filtering and humidifying attachment for registers and radiators, a casing-like shield comprising side walls, front and rear walls and a top, all occupying permanently fixed relation, a drawer-like water pan occupying a position wherein it is enclosed by said shield walls, said pan being slidable through the front shield wall to and from said position, said pan being spaced 1 passage and having its rear In testimony whereof, I aflix mysignature. 7
